Description
Technical Field
[0001] The present invention relates to the technical field of steel strip wiring, and in particular to a special-shaped steel strip wiring device. Background Art
[0002] Flexible hoses play an irreplaceable role in marine engineering. As key connectors in offshore oil and gas development, these pipeline systems primarily transport media between wellheads and floating production facilities, providing reliable assurance for the safe and efficient transportation of oil and gas resources. Their unique structural design combines excellent bending properties with fatigue resistance. This exceptional combination of properties enables the pipelines to withstand harsh conditions such as wind and wave impact and seawater corrosion, maintaining continuous operation for decades in complex sea conditions.
[0003] The flexible pipe's middle layer is equipped with a compressive armor layer, which is formed by wrapping special-shaped steel strips around the flexible pipe. During this process, the free end of the strip is fixed relative to the flexible pipe, which moves along its length. The payout shaft releases the strip, which then passes through a cable arrangement, a traction device, and a forming platform, rotating through a twisting mechanism and then onto a flexible hose or inner pipe with a carcass layer. Because the special-shaped steel strips are multi-layer, spirally wound coils with an axial dimension of approximately 1.5 meters, the payout shaft's release point is not constant; instead, the coils reciprocate along the payout shaft's axis. In existing technology, a fixed-position guide structure is provided. The special-shaped steel strip released from the payoff shaft is guided by the guide structure before being wound onto a flexible tube or an inner tube with a skeleton layer. This ensures that the angle at which the special-shaped steel strip is wound onto the flexible tube is consistent. However, the direction of travel of the steel strip between the guide structure and the payoff shaft is dynamic, and it is impossible to maintain it in an optimal direction. This results in uneven travel of the special-shaped steel strip, or causes damage such as creases, cracks, or plastic deformation during travel. How to ensure that the special-shaped steel strip travels smoothly and without damage during the unwinding process is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0009] Furthermore, the driving device is a motor, and the motor is connected to the swing bracket via a reducer.
[0010] Furthermore, a centering component is included, and the centering component includes: a swing seat connected to the steel belt receiving point; A swing head is swingably connected to the swing seat, wherein the swing axis of the swing head, the rotation axis of the wire guide roller, and the swing axis of the swing bracket are perpendicular to each other; A centering guide roller connected to the swing head, wherein the rotation axis of the centering guide roller is parallel to the swing axis of the swing head, and the two centering guide rollers are arranged at an axial distance from each other along the wire arrangement guide roller and respectively in rolling contact with two surfaces opposite to each other of the steel strip; a spring connecting the swing seat and the swing head, and configured to enable the swing head to swing adaptively relative to the swing seat; Limit blocks, two of which are mounted on the swing seat and are respectively located on both sides of the swing head along the swing direction; Photoelectric switches, two of which are mounted on the swing head and respectively detect the two limit blocks.
[0011] Furthermore, the spring is connected to the swing seat via a spring pull rod.
[0012] Furthermore, it also includes a tension balancing component, the tension balancing component including: A guide rail extending along the X-axis direction and connected and fixed to the swing bracket; A slider, connected and fixed to the cable bracket and slidingly engaged with the guide rail; an oil cylinder, connected to the swing bracket and the cable traversing bracket, and used to enable the cable traversing bracket to adaptively translate relative to the swing bracket; A pull-wire encoder is used to detect the position of the cable bracket on the guide rail.

[0015] The above technical solution of the present invention has the following advantages over the prior art: 1) The special-shaped steel strip arranging device of the present invention, by providing a swinging assembly and a arranging assembly, changes the position of the steel strip receiving point of the arranging bracket according to the position of the steel strip release point of the unwinding shaft during the steel strip unwinding process. The position of the steel strip receiving point changes with the position of the steel strip released from the pay-off shaft, so that the travel direction of the steel strip between the pay-off shaft and the arranging bracket can always maintain the optimal direction. The position of the steel strip output point of the arranging bracket is located at the swing axis of the swinging bracket and remains stationary. Therefore, the travel direction of the steel strip between the steel strip output point and the hose maintains a constant optimal direction, ensuring that the steel strip travels smoothly and is not bent.

Improve guidance stability and production efficiency, 2.1. Evenly distribute contact pressure: The semicircular structure makes the contact surface between the steel belt and the cable arranging device fit in an arc shape, which makes the pressure distribution more even and reduces local wear. It not only protects the surface finish of the steel belt but also extends the service life of the cable arranging device. 2.2. Suppressing motion deviation: During high-speed belt threading, the arc-shaped guide can effectively limit the lateral swing or twisting of the steel belt, ensuring its smooth operation on the preset path, reducing the frequency of shutdown adjustments, and improving production continuity; 3.

DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0020] In existing technology, the flexible hose manufacturing process requires wrapping a shaped steel strip around the surface to form a pressure-resistant armor layer. The strip's release point on the payoff shaft reciprocates along the axis, causing the strip's path to continuously change. Traditional guide structures are fixed and unable to dynamically adapt to deviations in the strip's release point. This can cause the strip to bend or become stuck during travel, impacting winding quality and production efficiency.
[0021] To address these issues, researchers discovered that the key lies in establishing a dynamic guiding mechanism. By analyzing the changing trajectory of the steel strip, they realized the need to compensate for path deviations caused by axial displacement of the strip's release point. Traditional fixed guiding structures lack position adjustment capabilities, causing the strip to bend and deform under stress. This led to the concept of using a swing assembly in conjunction with a cable arrangement assembly to create a spatial guiding system that adjusts in real time as the payout shaft's release point moves, maintaining the stability of the strip's directional trajectory despite dynamic changes.
[0022] See also Figures 1 to 9 As shown, an embodiment of the special-shaped steel strip wiring device provided by the present invention.
[0023] The special-shaped steel strip wiring device includes: A support assembly, comprising a support 11; The swing assembly includes a swing bracket 21 and a driving device 22. The swing bracket 21 swings around the X-axis, and the driving device 22 drives the swing bracket 21 to swing. The cable arrangement assembly includes a cable arrangement bracket 31 and a cable arrangement guide roller 32. The cable arrangement bracket 31 is connected to the swing bracket 21 and has a steel belt receiving point 311 and a steel belt output point 312. Multiple cable arrangement guide rollers 32 are arranged on the cable arrangement bracket 31. The rotation axis of the cable arrangement guide roller 32 is orthogonal to the X-axis direction. The steel belt receiving point 311 swings synchronously with the swing bracket 21, and the steel belt output point 312 is fixed at the swing axis position of the swing bracket 21.
[0024] In the above text, the support 11 is the installation base of the special-shaped steel strip wire arrangement device. The drive device 22 refers to the power device that generates mechanical swing, which is used to accurately control the swing angle and frequency. The steel strip receiving point 311 of the wire arrangement bracket 31 refers to the area where the steel strip enters the wire arrangement guide roller 32, and its spatial position is dynamically adjusted with the swing of the swing bracket 21. The rotation axis of the wire arrangement guide roller 32 is designed to be perpendicular to the X-axis to ensure that the wire arrangement guide roller 32 always maintains tangential contact with the steel strip 4 during the swing process. The steel strip output point 312 is fixed at the swing axis of the swing bracket 21, forming a stable output reference point that is not affected by the swinging motion.
[0025] Specifically, during operation, the payoff shaft's rotational axis extends along the Y-axis, and the wire traversing assembly is positioned to one side of the payoff shaft in the X-axis. When the payoff shaft's steel strip release point moves axially, the drive device 22 drives the swing bracket 21 to swing about the X-axis, causing the steel strip receiving point 311 of the wire traversing bracket 31 to shift synchronously. After exiting the payoff shaft, the steel strip 4 first enters the continuously adjusted steel strip receiving point 311, where it is guided by multiple wire traversing guide rollers 32 before exiting at the steel strip delivery point 312. The wire traversing guide rollers 32 counteract lateral friction during the steel strip's travel through rolling contact, ensuring a smooth transition along the tangent of the wire traversing guide rollers 32 during its swinging motion. The fixed position of the steel strip delivery point 312 ensures a constant final delivery direction for the steel strip 4, achieving an organic combination of dynamic adjustment and static output.
[0026] This technical solution achieves dynamic compensation of the strip's travel path during unwinding. The synergistic effect of the swing assembly and the cable assembly ensures that the strip receiving point 311 matches the displacement of the strip's release point in real time, while the strip output point 312 maintains a stable orientation. This structure effectively eliminates the problem of strip bending caused by movement of the strip's release point on the payoff shaft, ensuring smooth strip travel during dynamic changes, improving winding quality and equipment reliability.
[0027] In this embodiment, the plurality of wire guide rollers 32 are arranged in sequence along the arc direction and guide the steel belt 4 to move along the arc direction. The steel belts on the steel belt input side and the steel belt output side of the wire arrangement assembly both move along the tangent direction of the arc direction.
[0028] Arranging the plurality of wire-arranging guide rollers 32 in sequence along the arc direction means that the wire-arranging guide rollers 32 are arranged around a central point with equal spacing or variable spacing. This arrangement allows the steel strip 4 to maintain a uniform curvature change during the swinging process.
[0029] Specifically, when the steel strip 4 moves from the steel strip receiving point 311 to the steel strip output point 312, multiple wire guide rollers 32 guide the steel strip 4 to form a continuous arc path, eliminating the stress mutation caused by the right-angle turning point, so that the steel strip 4 maintains a smooth transition during the bending process, avoiding local bending or deviation of the travel trajectory.
[0030] The above technical solution ensures that the steel belt 4 always moves along a smooth curvature path, avoids material damage caused by local hard bending, and prevents the steel belt 4 from failing in guidance due to path deviation.
[0031] In this embodiment, the cable traversing bracket 31 adopts a semicircular bracket structure. The central axis of the semicircular bracket is parallel to the rotation axis of the cable traversing guide roller 32. Multiple cable traversing guide rollers 32 are arranged in sequence along the circumferential direction of the outer convex side of the semicircular bracket.
[0032] In the above description, a semicircular support refers to a support structure with a semicircular arc profile, whose convex side forms a continuous, smooth guide surface. The central axis of the semicircular support is parallel to the rotation axis of the wire guide roller 32, meaning that the bending direction of the semicircular support is orthogonal to the axial direction of the wire guide roller 32. This ensures that the travel direction of the steel strip 4 always aligns with the rolling direction of the wire guide roller 32.
[0033] Through the above technical solution, the cable arrangement bracket 31 meets the installation requirements of the cable arrangement guide roller 32 and has a more compact structure.
[0034] In this embodiment, the wire arrangement assembly also includes a limiting guide roller 33, which is installed on the wire arrangement bracket 31 and rolls in contact with the steel belt 4. The rolling axes of the limiting guide roller 33 and the wire arrangement guide roller 32 are parallel and the two are used to roll in contact with two opposite surfaces of the steel belt 4 respectively.
[0035] In the above, the limiting guide roller 33 and the wire arrangement guide roller 32 form a spatial positioning constraint on the steel strip 4 by rolling in contact with the steel strip on both sides.
[0036] Specifically, during the movement of the steel belt 4, the wire-laying guide roller 32 guides the steel belt to move along a predetermined path from the steel belt receiving point 311 to the steel belt output point 312, and the limiting guide roller 33 simultaneously applies rolling constraints to the other surface of the steel belt. The limiting guide roller 33 and the wire-laying guide roller 32 provide continuous rolling support from both sides of the steel belt, forming a two-way clamping effect to prevent the steel belt 4 from detaching from the wire-laying assembly.
[0037] Through the above technical solution, the present application solves the problems of deviation of the steel belt 4's travel trajectory, surface bending and poor travel caused by insufficient unilateral constraint during the dynamic swinging process, and realizes stable guidance and smooth travel of the steel belt 4 under the swinging condition.
[0038] In this embodiment, the driving device 22 is a motor, and the motor is connected to the swing bracket 21 via a speed reducer 23 .
[0039] The swing speed of the swing bracket 21 does not need to be too fast, so the speed reducer 23 is provided to keep the swing speed of the swing bracket 21 within an appropriate range.
[0040] In this embodiment, a centering component is also included, and the centering component includes: Swing seat 51, connected to the steel belt receiving point 311; The swing head 52 is swingably connected to the swing seat 51, and the swing axis of the swing head 52 is perpendicular to the rotation axis of the wire guide roller 32 and the swing axis of the swing bracket 21; A centering guide roller 53 is connected to the swing head 52. The rotation axis of the centering guide roller 53 is parallel to the swing axis of the swing head 52. The two centering guide rollers 53 are arranged at a distance along the axial direction of the wire arrangement guide roller 32 and respectively roll in contact with the two opposite surfaces of the steel strip 4. A spring 54 connects the swing seat 51 and the swing head 52 to enable the swing head 52 to swing adaptively relative to the swing seat 51; Limit blocks 55, two of the limit blocks 55 are mounted on the swing seat 51 and are respectively located on both sides of the swing head 52 along the swing direction; Photoelectric switch 56 , two photoelectric switches 56 are installed on the swing head 52 and detect the two limit blocks 55 respectively.
[0041] Among them, the swing seat 51 refers to a mounting base fixed to the steel strip receiving point 311, which is used to support the swinging motion of the swing head 52. The swing axis of the swing head 52 is perpendicular to the rotation axis of the wire guide roller 32, which can be achieved by a hinged structure to form a three-dimensional spatial degree of freedom, ensuring the dynamic adjustment of the steel strip's travel direction. The rotation axis of the centering guide roller 53 is parallel to the swing axis of the swing head 52, and the steel strip 4 passes between the two centering guide rollers 53. The spring 54 connects the swing seat 51 and the swing head 52, which can be achieved by a tension spring 54 or a compression spring 54, so that the swing head 52 can maintain its position and adaptively swing and reset under the action of external force. The limit block 55 refers to a physical blocking structure arranged on both sides of the swing path of the swing head 52, which can be achieved by a metal block or a high-strength plastic block fixed to the swing seat 51. Its function is to limit the maximum swing angle of the swing head 52. The photoelectric switch 56 is a sensor that detects position by switching on and off a light beam. Specifically, it can be a reflective or through-beam photoelectric sensor installed on the swing head 52. Its function is to sense the triggering state of the limit stop 55 in real time. The limit stop 55 and the photoelectric switch 56 detect the extreme positions of the swing head 52. As the swing head 52 swings around its axis, the photoelectric switches 56 on either side of the swing head 52 move synchronously with it. The photoelectric switches 56 on either side operate independently. When either side detects the limit stop 55, they immediately generate an electrical signal that is fed back to the control system, accurately determining that the swing head 52 has reached the preset swing position on that side.
[0042] Specifically, after the steel strip 4 is released from the pay-off shaft, it passes between the two centering guide rollers 53. When the steel strip release point of the pay-off shaft moves horizontally from the first end to the second end of the pay-off shaft, the steel strip 4 contacts one of the centering guide rollers 53 and drives the swing head 52 to swing to one side relative to the swing seat 51. When one of the photoelectric switches 56 detects the limit block 55 on one side, the swing assembly drives the wire arranging assembly to swing forward. When the steel strip release point of the pay-off shaft moves horizontally from the second end to the first end of the pay-off shaft, the steel strip 4 contacts the other centering guide roller 53 and drives the swing head 52 to swing to the other side relative to the swing seat 51. When the other photoelectric switch 56 detects the limit block 55 on the other side, the swing assembly drives the wire arranging assembly to swing in the opposite direction.
[0043] Through the above technical solution, by detecting the real-time position of the steel belt release point of the pay-off shaft and controlling the swing of the cable arrangement bracket according to the real-time position of the steel belt release point, it is ensured that the steel belt receiving point and the steel belt release point of the pay-off shaft remain matched.
[0044] In this embodiment, the spring 54 is connected to the swing seat 51 through a spring pull rod 57.
[0045] The spring pull rod 57 is a rigid rod with two ends connected, specifically a metal rod with threaded joints, which is used to establish a mechanical connection between the spring 54 and the swing seat 51. This structure transmits elastic force through the axial rigidity of the rod, maintaining the extension and retraction trajectory of the spring 54 in a linearly constrained state.
[0046] Specifically, when the swing head 52 swings due to the tension of the steel belt, the spring pull rod 57 converts the elastic deformation of the spring 54 into linear motion along the rod's axis, ensuring that the tension of the spring 54 always remains perpendicular to the swing plane of the swing head 52. The connection points at both ends of the spring pull rod 57 form an articulated connection with the ends of the spring 54 and the swing seat 51, respectively, allowing the rod to adapt to the spatial displacement of the swing seat 51 while transmitting the elastic force. This connection ensures that the spring 54 forms a stable mechanical transmission path between the swing seat 51 and the swing head 52, preventing radial torsional loads on the spring 54 caused by angular deviation.
[0047] Through the above technical solution, the present application solves the problem of spring 54's connection structure being susceptible to deflection and wear during dynamic swinging, ensuring that spring 54 always remains axially centered. This structure avoids the risk of elastic failure due to connection point offset, allowing the centering assembly to maintain a constant restoring force when the steel strip's travel direction is adjusted, thereby ensuring that the path of the steel strip is offset during winding.
[0048] In this embodiment, a tension balancing component is also included, including: The guide rail 61 extends along the X-axis direction and is connected and fixed to the swing bracket 21; The slider 62 is fixedly connected to the cable bracket 31 and slides with the guide rail 61; The oil cylinder 63 is connected to the swing bracket 21 and the cable traversing bracket 31 and is used to make the cable traversing bracket 31 move adaptively relative to the swing bracket 21; A pull-wire encoder (not shown in the figure) is used to detect the position of the cable bracket 31 on the guide rail 61.
[0049] The guide rail 61 is a guide member extending linearly along the X-axis, which is fixedly connected to the swing bracket 21 and is used to constrain the translation trajectory of the cable bracket 31. The slider 62 is a moving component that forms a sliding fit with the guide rail 61 and realizes its linear motion along the X-axis by connecting to the cable bracket 31. The working pressure of the oil cylinder 63 is relatively high and the oil cylinder 63 is set to a fixed pressure. Figure 5Where L is the stroke of the oil cylinder 63. A pull-wire encoder measures the translational position of the cable traversing bracket 31. As the cable traversing assembly oscillates, the position of the steel strip constantly changes. To maintain constant tension on the steel strip, the payout speed must be adjusted in real time. Because the oil cylinder pressure is maintained within a certain range, any position change in the cable traversing bracket 31 indicates a change in tension on the steel strip. Therefore, the payout shaft speed must be controlled to maintain constant tension.
[0050] Through the above technical solution, the present application can compensate in real time for the changes in steel belt tension caused by the axial movement of the steel belt release point and the swing of the cable arrangement assembly, ensuring that the steel belt is subjected to constant tension during movement.
[0051] In this embodiment, the oil inlet of the oil cylinder 63 is connected to the gas outlet of the nitrogen tank 66 .
[0052] A pressure gauge 67 is provided at the gas outlet of the nitrogen tank 66 , and the gas outlet of the nitrogen tank 66 is connected to the oil inlet of the oil cylinder 63 through a high-pressure gas pipe 68 .
[0053] According to the process requirements, nitrogen gas of different pressures is filled into the nitrogen tank 66 to provide a tension. The real-time position of the cable tray 31 is detected by a pull-rope encoder, and the position signal is fed back in real time to control the pay-off motor so that the pay-off rack remains in the set position. The PLC adjusts the pay-off speed in real time according to the set tension to keep the tension constant.
[0054] The advantages of using nitrogen to drive the cylinder extension are as follows: Stepless cushioning and constant pressure output: Nitrogen accumulators store energy through compressed gas to provide continuously adjustable damping force. Compared with traditional springs or mechanical brakes, their pressure output is stepless and has no mechanical hysteresis.
[0055] High-speed dynamic response: The nitrogen system has a fast response time and can quickly compensate for sudden tension changes caused by the inertia of the tape reel or the elastic deformation of the tape (such as emergency stops and acceleration conditions), avoiding tape breakage or loose lamination.
[0056] Anti-pollution and long life: Nitrogen is an inert gas with no oxidation risk. The system sealing design can withstand dust and oily environments, and the maintenance cycle is extended to 2-3 times that of traditional hydraulic systems.
[0057] Fail-safe mechanism: The nitrogen system has built-in pressure redundancy, which can maintain the basic tension in the event of power outage or sensor failure, preventing uncontrolled strip collapse.
[0058] In this embodiment, the tension balancing assembly further includes a sensing bracket 64 and a proximity switch 65. The sensing bracket 64 is connected to the cable bracket 31. The two proximity switches 65 are connected to the swing bracket 21 at intervals along the X-axis direction. The two proximity switches 65 are respectively arranged on both sides of the sensing bracket 64 along the X-axis direction. The two proximity switches 65 are used to detect the sensing bracket 64.
[0059] As mentioned above, the sensing bracket 64 is a metal structure rigidly connected to the cable bracket 31. Specifically, it can be formed by welding L-shaped steel plates. When it moves synchronously with the cable bracket 31, it triggers the sensing area of the proximity switch 65. The proximity switch 65 is a non-contact position detection sensor, specifically an inductive or capacitive sensor. Two proximity switches 65 are spaced apart along the X-axis to form a physical limit detection point. When the sensing bracket 64 enters its sensing range, it outputs a switch signal.
[0060] Specifically, as the cable traversing bracket 31 translates along the X-axis, the sensing bracket 64 moves synchronously with it. When it reaches the preset travel endpoint, the sensing bracket 64 enters the sensing range of a proximity switch 65 on either side, triggering the corresponding switch signal. Upon receiving the proximity switch 65 signal, the control system immediately stops the payout motor from paying out or taking up the wire, preventing the cable traversing bracket 31 from exceeding the set travel range.
[0061] Through the above technical solution, the physical limit detection formed by the proximity switch 65 prevents mechanical damage caused by over-travel movement.
[0062] In this embodiment, the bracket assembly includes the two supports 11 , and both ends of the swing bracket 21 are connected to the two supports 11 respectively.
[0063] In response to the tension fluctuations and tape damage caused by trajectory mismatch during the unwinding process of the existing wire tracing device, the present invention provides a semicircular dynamic tracking wire tracing device. Through the synergistic effect of the arc-shaped wire tracing frame and closed-loop tension control, the synchronous and precise regulation of the tape release position and tension is achieved, thereby overcoming the winding quality problems caused by poor structural rigidity and response lag in traditional technologies.
